Answer:

Fossils are the remains of ancient plants and animals that were buried millions of years back. These are found to be embedded in the sedimentary types of rocks. The earliest known direct fossils are not obtained in the present day, but the imprints of these fossils are explored in many of the places. These were the ancient micro-fossils such as bacterias, cyanobacteria that existed about 3.5 billion years back.

Some of the direct evidence of fossils are obtained from the rocks in the western part of Australia and the southwestern part of Greenland.

Thus, the imprints of these fossils are found in many rocks at different places, and this suggests the existence of life during that particular time frame.

Generally speaking do athletes typically have a higher or lower resting heart rate? explain

Stells [14]

Athletes tend to have lower resting heart rates because training programs that build speed, fitness, muscle and endurance also train your heart muscles to pump a higher volume of blood with each heartbeat.

1) Glycogen phosphorylase catalyzes the removal of glucose from glycogen. The ∆G°’ for this reaction is 3.1 kJ/mole 1. Calculate

Andru [333]

Answer:

1. G° = -RT ln (G1P/P)

3.1 = 8.314 × 310 × ln (G1P/P)

3.1 / 2577.34 = ln (G1P/P)

0.0012 = ln (G1P/P)

0.0012 = (log G1P/P)/log 2.71828

0.4342 × 0.0012 = log G1P/P

0.00052 = log G1P/P

G1P/P = 10^0.00052 = 1.0012

P/G1P = 1/1.0012 = 0.9988

2. The cleavage of glycogen phosphorolytically is beneficial for the cell to conduct the process as the discharged glucose is phosphorylated. A general hydrolytic cleavage would give rise to only a glucose, which has to be phosphorylated again with the help of ATP.

Another merit of phosphorylated glucose is that it comprises the negative charge and cannot diffuse out of the muscle cell. Thus, the reaction will not be at equilibrium under the physiological conditions and always encourages the generation of the products. The formation of products will amend the change in free energy in such a manner that the reaction will always carry in the forward direction.

3. Greater the ratio of [Pi]/[glucose-1-phosphate], higher will be the relative rate of glycogen phosphorylase in comparison to the phosphoglucomutase as the transformation of Glu-1-P becomes slow because of lesser accessibility of substrate.
